Direct Mail Marketing Question

[Kelli Thomas]

Hi everyone! I am a fairly new real estate agent trying to generate some leads. I have been sending out direct mail marketing letters (handwritten by me) over the last few weeks. My letters are going out to my hometown and targeting people who have lived in their home for 5+ years, hopefully getting them to want to sell and use my services. 

My letters are pretty short right now stating I can help them get their home sold, that I grew up in this area and love it and to contact me to talk about their home. 

How much time do you typically wait before sending a follow up letter? Do you change the verbiage on your follow up letters?

Thank you!!
